SEMICONDUCTOR DEVICES INCLUDING VERTICAL CELL STRINGS THAT ARE COMMONLY CONNECTED

摘要

A semiconductor device includes bit lines on a substrate, a gate structure provided between the substrate and the bit lines, a common source line provided between the gate structure and the bit lines, and channel structures connecting the bit lines to the common source line. Each of the channel structures may include a plurality of first vertical portions penetrating the gate structure and being connected to the bit lines, a second vertical portion penetrating the gate structure and being connected to the common source line, and a horizontal portion provided between the substrate and the gate structure to connect the first and second vertical portions to each other.
